Title: Method for surface treatment
Inventor: TAKEI HIDEO
IPC: H01L21/302
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To increase light absorption efficiency by forming texture on a Si or GaAs substrate or the like used for a solar cell panel to reduce reflectance of the panel surface. SOLUTION: In this surface treatment, surface of a semiconductor substrate 3 is plasma etched with a plasma etching equipment in which the semiconductor substrate 3 is grounded, wherein a gas mixture comprising SF6 gas containing fluorine atoms in the molecule and HCl gas containing a chlorine atom in the molecule is used. Because of the etching rate difference between SF6 gas and HCl gas for the same crystallographic plane, the etching becomes hard to proceed in isotropic basis, and texture is produced on the surface of the semiconductor substrate 3 even with plasma etching equipment of low impact energy. Therefore, because any apparatus for insulating the substrate side electrode against substrate carrying mechanism is not necessary, the equipment cost is reduced, and the cost of solar cell panel is reduced.
